Plot for separation of azimuthal angle (delta_phi)

Asked by sudesh gupta

Hi

I'm trying to plot cross section with respect to separation of azimuthal angle (delta_phi) between a particle (for example electron) and jet (which is required). I 'm familiar with plot for two particles but when I consider 1 jet and a particle, what changes I'm supposed to do in plot card? I'm putting small section of plot card.

# Put here your list of classes
#**************************************************************************
jet 1 -1 2 -2 3 -3 4 -4 21 # Class number 1
e 11 -11
mET 12 -12 14 -14 16 -16 1000022 # Missing ET class, name is reserved
# End Classes # This is TAG. Do not modify this line
#**************************************************************************

# Put here the required plots
#**************************************************************************
delta_phi 2 2
# End PlotDefs # This is TAG. Do not modify this line
#***********************************************************************

MadAnalysis4 is out of support since a couple of years already (since 2012 orr 2013).
I would suggest to pass to MadAnalysis5, since I do not remember how MA4 was working for that case.

Cheers,

Olivier

Thank you very much for help.

I installed MadAnalysis5 and what I figured out is as follows;

1.) I didn't find delta_phi in MaadAnalysis5. If it is available, where can I find?

2.) delta_phi function is defined in MadAnalysis4 (inside kin_func.f) but I have some issue like, I want to plot three delta_phi distributions (for three different cases) in single plot. I didn't find any feature for that. If this feature is available, please let me know how can I proceed. And I guess which will work for MA5 also.

Thank you

Hi

Please try

plot DPHI_0_PI (j[1], e+[1]) 10 0 4

this will plot delta phi between leading jet and leading positive charged electron.(just as an example)

for details please see madanalysis manual or webpage.

Cheers
Jack
